與片段

Question

隨着新的Android和與Facebook SDK但Facebook的登錄嘗試通過以下的link

登錄因爲他們說會做的登錄過程與Facebook，但沒有發生，且每次顯示註銷狀態。 這裏是活動課。

public class MYFaceLoginActivity extends FragmentActivity { 

     private LoginFragment loginfragment; 

     /** Called when the activity is first created. */ 
     @Override 
     public void onCreate(Bundle savedInstanceState) { 
      super.onCreate(savedInstanceState); 
      // TODO Auto-generated method stub 
      if(savedInstanceState==null) 
      { 
       loginfragment=new LoginFragment(); 
       getSupportFragmentManager().beginTransaction().add(android.R.id.content, loginfragment).commit(); 

      } 
      else 
      { 
       loginfragment=(LoginFragment) getSupportFragmentManager().findFragmentById(android.R.id.content); 
      } 


     } 

     @Override 
     protected void onActivityResult(int requestCode, int resultCode, Intent data) { 
      // TODO Auto-generated method stub 
      super.onActivityResult(requestCode, resultCode, data); 
      //loginfragment.onActivityResult(requestCode, resultCode, data); 
     } 

    } 

其次是片段類

public class LoginFragment extends Fragment 
{ 
    private View login_view; 
    private static final String TAG="LoginFragment"; 
    private UiLifecycleHelper uihelper; 
    private LoginButton authbutton; 

    private Session.StatusCallback callback=new Session.StatusCallback() { 

     @Override 
     public void call(Session session, SessionState state, Exception exception) { 
      // TODO Auto-generated method stub 
      onSessionStatechange(session, state, exception); 
     } 
    }; 

    @Override 
    public View onCreateView(LayoutInflater inflater, ViewGroup container, 
      Bundle savedInstanceState) { 
     // TODO Auto-generated method stub 
     login_view=inflater.inflate(R.layout.login_fragment, container,false); 

     authbutton=(LoginButton) login_view.findViewById(R.id.authButton); 
     authbutton.setFragment(this); 
     authbutton.setReadPermissions(Arrays.asList("user_likes","user_status")); 

     return login_view; 
    } 

    private void onSessionStatechange(Session session,SessionState state,Exception exception) 
    { 
     if(state.isOpened()){ 
      Log.i(TAG, "LOGGED IN...."); 
     } 
     else 
     { 
      Log.i(TAG, "LOGGED OUT...."); 
     } 
    } 

    @Override 
    public void onCreate(Bundle savedInstanceState) { 
     // TODO Auto-generated method stub 
     super.onCreate(savedInstanceState); 
     uihelper=new UiLifecycleHelper(getActivity(), callback); 
     uihelper.onCreate(savedInstanceState); 
    } 

    @Override 
    public void onResume() { 
     // TODO Auto-generated method stub 
     super.onResume(); 
     Session session=Session.getActiveSession(); 
     if((session!=null)&&(session.isOpened()||session.isClosed())) 
     { 
      onSessionStatechange(session, session.getState(), null); 

     } 
     uihelper.onResume(); 
    } 

    @Override 
    public void onPause() { 
     // TODO Auto-generated method stub 
     super.onPause(); 
     uihelper.onPause(); 
    } 
    @Override 
    public void onSaveInstanceState(Bundle outState) { 
     // TODO Auto-generated method stub 
     super.onSaveInstanceState(outState); 
     uihelper.onSaveInstanceState(outState); 
    } 
    @Override 
    public void onDestroy() { 
     // TODO Auto-generated method stub 
     super.onDestroy(); 
     uihelper.onDestroy(); 
    } 

    @Override 
    public void onActivityResult(int requestCode, int resultCode, Intent data) { 
     // TODO Auto-generated method stub 
     super.onActivityResult(requestCode, resultCode, data); 
     uihelper.onActivityResult(requestCode, resultCode, data); 
    } 
} 

任何人都可以指出我在做錯誤的here.Thanks任何答覆，這個Facebook登錄新的3.0卡住三服。

Answer 1

看看這個例子，也許事情會變得清晰。我沒有試過運行它，但我希望它沒有任何問題。

Answer 2

請改變​​文件

getSupportFragmentManager().beginTransaction().add(
    android.R.id.content,loginfragment).commit(); 

insted的使用：

getSupportFragmentManager().beginTransaction().add(R.id.content, loginfragment).commit(); 
loginfragment=(LoginFragment) getSupportFragmentManager().findFragmentById(R.id.content);
